libgo patch committed: scan register backing store on ia64


This libgo patch by James Clarke scans the register backing store on
ia64 when doing a Go garbage collection.  On ia64, a separate stack is
used for saving/restoring register frames, occupying the other end of
the stack mapping. This must also be scanned for pointers into the
heap.  Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.
Committed to mainline.
